The International Olympic Committee signaled its frustration with the court ruling Wednesday.

"It's unfortunate that the evidence used in this proceeding is not now being made available to anti-doping organizations to further the fight against doping," it said in a statement.

British No.1 Murray went public in February with his demand for more blood testing in tennis, saying it needed to do everything it could "to ensure that everyone competing at the highest level and below is clean."

He was joined by fellow grand slam winners Roger Federer, Novak Djokovic and Rafael Nadal in demanding stricter tests and in March the International Tennis Federation announced it would be introducing a Biological Passport program - a more stringent control against doping.
